Total cost of ownership vs acquisition price: the wrong number drives most decisions

Total cost of ownership vs acquisition price: the wrong number drives most decisions

Vehicle procurement decisions in most fleet operations are made primarily on acquisition price.

Acquisition price typically represents 25–35% of the total cost of owning and operating a vehicle across its life. The remaining 65–75% — fuel, maintenance, tyres, insurance, administration, and residual value loss — accrues after the purchase decision is made.

The Chartered Institute of Procurement and Supply documents that organisations using total cost of ownership (TCO) analysis as the primary basis for fleet procurement decisions achieve 8–22% lower lifetime fleet costs than those using acquisition price as the primary criterion.

A documented example

Fleet News UK analysis comparing two equivalent 18-tonne rigid trucks across a 500,000km lifecycle: the truck with a £8,000 lower purchase price but 12% higher fuel consumption costs £47,000 more over its operational life — making it the more expensive option by a ratio of nearly 6:1 on the cost difference.

The TCO components most purchase decisions ignore

• Fuel consumption variance — measurable from manufacturer data and real-world telematics datasets before purchase.
• Maintenance cost variance — available from manufacturer service interval data and from fleet operators running the same vehicle types.
• Parts availability and cost — critically important in markets with limited dealer networks.
• Residual value — the Sewells Group documents that residual value differences between equivalent specification trucks from different manufacturers can represent 15–25% of original purchase price in Sub-Saharan African markets.

TCO calculation requires five inputs

1. Acquisition cost plus estimated financing cost.
2. Estimated fuel consumption at projected annual mileage, multiplied by fuel cost.
3. Historical maintenance cost per kilometre for the vehicle type.
4. Insurance cost.
5. Estimated residual value at planned disposal point.

Five inputs. One number. A significantly better procurement decision.
